PROBLEM TO BE SOLVED: To provide a sound signal correction device for preventing starting deterioration in a speaker by correcting a sound signal by digital processing. SOLUTION: The sound signal correction device is provided with: difference acquiring means 11 to 15 and 21 to 25 for acquiring difference between digital data constituting an input sound signal and data before one or several samples; and correcting means 16, 17, 26 and 27 for performing correction that increases a value more about certain data as the difference becomes large on the basis of the difference acquired by the difference acquiring means. Correction by the correction means is performed when the difference is equal to or greater than a prescribed value. The correction is such correction where, for example, the larger the difference is, the more the value increases as in an exponential function. COPYRIGHT: (C)2010,JPO&INPIT
